74LVC594APW,118

Shift Registers Overview

The Nexperia 74LVC594APW,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register. It operates within a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes separate clock and reset inputs for both the shift and storage registers, enabling independent control. Data shifts on LOW-to-HIGH transitions of the SHCP input, while transfer to the storage register occurs on STCP transitions. It supports partial power-down via IOFF circuitry and complies with JEDEC standards.

Shift Registers Feature Summary

• Features Schmitt-trigger action at all inputs for tolerance of slower rise and fall times
• Includes IOFF circuitry to disable outputs during partial power-down mode
• Provides separate clock and reset inputs for shift and storage registers
• Supports direct interface with TTL levels and mixed 3.3 V/5 V environments

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVC594A series is available in multiple packages including SO16, TSSOP16, DHVQFN16, and DHXQFN16. Confirm that the temperature range specification aligns with the operational requirements, as the datasheet specifies operation from -40 °C to +125 °C. Ensure compatibility with the intended supply voltage range of 1.2 V to 3.6 V before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with a dedicated storage register is required for serial-to-parallel conversion. It is suitable for applications involving mixed voltage domains due to its 5.5 V tolerant inputs. Consider the TSSOP16 package for space-constrained designs requiring surface mount technology. Verify that the operating temperature range meets the environmental conditions of the target application.

Shift Registers Part Context

This part belongs to the 74LVC594A family of 8-bit shift registers manufactured by Nexperia. The 'PW' suffix indicates the TSSOP16 plastic thin shrink small outline package (SOT403-1). The '118' suffix typically denotes tape and reel packaging, though verification with the manufacturer is recommended. The device is part of a broader portfolio of logic ICs designed for low-power and high-speed applications.

Shift Registers Replacement Considerations

Check for equivalent parts from other manufacturers offering similar 8-bit shift register functionality with compatible pinouts and electrical characteristics. Ensure any replacement supports the same supply voltage range and input voltage tolerances. Verify package dimensions if mechanical constraints are critical.
